Chemistry Sc1 Justin Barauskas No 9 How does the mass of copper plated in the electrolysis of copper sulphate solution vary with the current used? Aim The aim of this experiment is to find out relationship between the mass of copper deposited on the cathode and the (variable) current used. Planning First of all the factor I am going to vary in this experiment is the current. When the current is varied for example if it is big, the mass of copper deposited will be larger than with a small current. This is because when there is more current there are more electrons flowing therefore more copper deposited. So really the reason for more copper deposited is that, because there are more electrons flowing at the same time the anode loses copper ions quicker and the cathode gains copper ions quicker and deposits them as copper atoms. Therefore the ionic reactions happen faster...
